How to select the right hydraulic hose for your application


Shijiazhuang Standards Rubber Products Co., Ltd Is a highly professional and experienced manufacturer of rubber hoses in China. We have specialized in this field over 20 years and always dedicated to the producing of rubber hoses in high quality, with a wide range of demands from multiple industries, including engineering, ocean, mining, chemicals plastics, transportation, oil, metallurgy, etc. 


Our Products Include: Hydraulic Hose, Hot Oil Hose, Low Temperature Hose, Washer Hose, Fuel/Oil Hose, Gasoline Hose, Steam Hose, A/C Hose, Silicone Hose, Drilling Hose, Suction & Delivery Hose, Concrete Placement Hose, Hose Fitting & Hose Assembly, Etc.


With so many types of hydraulic hoses, how can we choose the right one for us? The following content will reveal the answer for you. Before you specify your next hose for that important application, use our Medium, Size, Flexibility, Pressure, Temperature, and Application six steps to ensure you have the right product for the application.



When considering hose pressure, it's important to know both the system working pressure and any surge pressures and spikes. Hose selection must be made so that the published maximum working pressure of the hose is equal to or greater than the maximum system pressure. Surge pressures or peak transient pressures in the system must be below the published maximum working pressure for the hose.


All hydraulic hoses have passed the industry rated specifications for burst pressure and carry a 4:1 design factor unless otherwise noted. Burst pressure ratings for hose are for manufacturing test purposes only. They are not an indication that the product can be used above the published maximum working pressure.


Care must also be taken when looking at the “weakest link” of the hose assembly. A hose assembly is rated at the maximum working pressure of the hose and the fitting component. Therefore the maximum working pressure of the hose assembly is the lesser of the rated working pressure of the hose and the end connections used.


Pressure spikes can occur during machine operation in an instant. They can occur so quickly in fact, that standard glycerin filled gages will never detect them.



When specifying hose, there are two temperatures you need to identify. One is the ambient temperature, which is the temperature that exists outside the hose where it is being used; the other is the media temperature, which is the temperature of the media conveyed through the hose. Very high or low ambient temperatures can have adverse affects on the hose cover and reinforcement materials, resulting in reduced service life.


Media temperatures can have a much greater impact on hose life. For example, rubber loses flexibility if operated at high temperatures for extended periods. Rubber hoses carry different temperature ratings for different fluids.Some media can increase or decrease the effects of temperature on the hose. The maximum rated temperature of a hose is specific to the media.


For example, hot oil hose has a temperature range of -67°F to + 275°F (-55°C to +135°C) for petroleum-based hydraulic fluids. However for water, water/glycol, and water/oil emulsion hydraulic fluids, the range drops to a rating of up to +185°F (+ 85°C). Air is rated even lower at up to 158°F (+ 70°C).

Some media can increase or decrease the effects of temperature on the hose. The maximum rated temperature of a hose is specific to the media.



Before selecting a hose, it is important to consider how the hose assembly will be used. Answering the following questions may help:

What type of equipment is involved?

What are the environmental factors?

Are mechanical loads applied to the assembly?

Will the routing be confined?

What about hose fittings – permanent or field attachable?

Will the assembly be subjected to abrasion?

Sometimes specific applications require specific hoses. For example, applications where hoses will encounter rubbing or abrasive surfaces would best be handled by our family of abrasion-resistant hoses with both tough and super tough covers. When application space is tight, bend radius is another important consideration.

Standards Rubber hydraulic hoses meet or exceed standards such as:

SAE (Society of Automotive Engineers)

EN (European Norm)

DIN (Deutsche Institute fur Normung)

ISO (International for Standardization Organization)


I believe that through the above introduction, everyone already knows how to choose the right hydraulic hose for your application.We sincerely welcome partners all over the world to visit us for win-win cooperation!


We are professional, friendly and businesslike Cooperation with suppliers helps us become faster and better.Every thing we do is customer-oriented.Quality is the top priority of system planning.
